Amazingly professional heating and air conditioning installers and service people!! I knew them as Ray Heating (here in the Reno, NV area for decades!)...now morphed into RHP...same stellar group. I decided to replace the 30 year old original equipment furnace to increase efficiency and to just get ahead of any failure of this original builders grade furnace. Costco had entered into a 'deal with Lennox and RHP...being a Costco member who values their choices this was a no brainer for me. The salesman, Troy Wilcox, wanted to have a few furnaces for me to choose from but the interior closet arrangement of my home limited the Lennox furnace choice to their most efficient top of the line model, SLP98DFV. My 30 year old starter home did not warrant such a beauty but since I plan on living here until I go out in a box the slightly higher cost seemed inconsequential to me. The installation was incredibly simple...the workers were friendly, professional and wonderfully clean, leaving nothing but a delightful new furnace in their wake. This was April 2011, the tail end of our heating season. All went well. Two months after the beginning of our new heating season the furnace was failing in some very odd ways. RHP was out in no time and these were not just parts replacers...their repair people are diagnostic experts giving me their full attention. The commercial installers who came to conduct the repair were, again, friendly, professional and pursued the repair to a happy conclusion leaving me with nothing but respect and gratitude for them. We were never without heat during the event, though chilled initially. I love the quiet soft heat of this furnace...since it is mounted in an internal closet near the bedrooms this made a huge difference in our winter sleeping. The filter we have on this unit would do a hospital proud. I want to thank the repair folks we saw and give them all a huge round of applause. I am recommending RHP to everyone who mentions heating or air conditioning needs...and those talking about remodeling, too. HOORAY for RHP!!
